Concept introduction:
Acyl chloride:
(e)
Interpretation:
The mechanism for the chlorosulfonation is to be proposed.
(f)
Interpretation:
The synthesis and structural formula for the step 9 has to be proposed.
(h)
Interpretation:
The possible stereoisomer’s has to be shown if the product is chiral.
Concept introduction:
Isomer: A molecule having the same molecular formula but with different chemical structure is called isomer.
Enantiomers: A compound which is non-superimposable mirror image is called enantiomers.
Diastereomers: A compound which is non-superimposable and non-mirror image is called diastereomers.
Racemic mixture: A racemic mixture is simply a mixture containing an equal amount of each enantiomer.
Achiral:
A molecule is superimposable on its mirror image is called achiral molecule.

- Nonearrow_forwardUnshared, or lone, electron pairs play an important role in determining the chemical and physical properties of organic compounds. Thus, it is important to know which atoms carry unshared pairs. Use the structural formulas below to determine the number of unshared pairs at each designated atom. Be sure your answers are consistent with the formal charges on the formulas. CH.
